Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• W : indicates side identified with part number.

f

•

: internal component.

• b : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

• : carbon pattern Caution:

Pattern face side: Parts on the pattern f ace side seen from (Conductor Side) the pattern face are indicated. Parts face side: Parts on the par ts face side seen from (Component Side) the parts face are indicated.

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

f

•

: internal component.

4

W or less unless otherwise

• 2 : nonflammable resistor.

• 4: printed coil.

• C : panel designation.

• U : B+ Line.

• H : adjustment for repair.

• Power voltages are dc 9 V and fed with regulated dc pow er supply from external power voltage jac k (J2) on the BASE MAIN board, dc 12 V and fed with regulated dc power supply from modular jack (J1) on the BASE MAIN board with 100 Ω in series, and dc 3.6 V and f ed with regulated dc power supply from battery terminal on the HAND MAIN board.

• Voltages and wav eforms are dc with respect to ground in test mode.

• Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.

• Signal path.
